12 Claims.

This invention relates to amachine for automatically embossing sections of sheet metal, for example sheet metal sections to be used as roofing wherein the lateral sides of the sections have interlocking relation with adjoining sections and the outer ends of the sections overlap the adjoining forward sections in a manner to prevent intake of water due to capillary attraction. One object of the invention is to provide an improved machine of this character wherein sheet metal sections may be fed to and through the machine and-hutomatically embossed transversely' to their direction of movement.-

Another object of the invention is to provide an improved machine of this character capable of embossing sheet metal on lines parallel to and transversely to their direction of movement.

Another object of the invention is to provide an improved machine of this character wher in sections of sheet metal are fed therethro gh and embossed, the sections serving as the means for operating the embossing devices.

A further object of the invention is to provide an improved machine of this character that is relatively simple and has large capacity.

Other objects of the invention will be apparent to those skilled in the art to which'my invention relates from the following description taken in connection with the accompanying drawings,

In the drawings, I indicates as an entirety a frame forming a support for a plurality of pairs Cleveland, Ohio, asslgnor to Cleveland, Ohio, a corpo- 1938, Serial No. 222,890

of standards 2,3, 4, 5, 6, I, 8 and 9. The standards 2, 3, 4, 5, 6 and 1 are shaped to form guides and seats for upper and lower pairs of bearing boxes II), which removably support upper and lower, shafts 2a, 3a, 4a, 5a, 6a and la. The shafts extend beyond the standards at one side of the frame I, the extended ends of each upper and lower shaft being geared together to rotate in opposite directions and one thereof being drivingly connected to a shaft H, the gearing between each upper and lower shaft and the driving connection with the shaft II being enclosed in a housing l2. The shaft II is provided with a pulley or sprocket l3 driven by an endless member H from a pulley or sprocket l5, which is fixed to the shaft of a motor l6.

The upper and lower shafts 2a, 3a, etc. are provided with rolls 2a, 3a, 4a, 5a, 6a, la, respectively. Each roll may be integral with the adjacent shaft or removably mounted thereon; in this latter arrangement each roll may be formed as .a single member or in sections and suitably keyed to the shaft.

Each section of sheet material A is delivered to the first set of rolls 2a manually or by a .suitable delivery mechanism (not shown), being, positioned on a guide indicated as an entirety at l1 disposed in position to direct the sections between the rolls 2a. The guide I! consists of a pair of spaced brackets Ila having cross bars IIb, an-. gles flc being secured to the arms of the brackets "a and an intermediate supporting strip I'Id being mounted on the bars llb.

'I'hesections of sheet metal A are embossed longitudinally along their lateral sides, as shown at a, a',..a and .by preference the sections are embossed longitudinally between its lateral portions, for example, centrally, as shown at B;' the sections are also embosse djransversely as shown at C, C, at either side of the embossmer it B; but where the embossment B is omitted, the embossments C, C, may extend entirely across the ends of the sections within the embossments a, 'a. When laid in position to form. a roof, the embossments a, a, a provide for an interlocking relation between each section and the adjoining sections, whereas (a) the embossments C, which are disposed adjacent the outer end of under pressure when the section is secured in position.

To form the embossment B as each section of material moves between the sets of rolls, 2a, 30., etc. each upper roll is formed with a substantially V-shaped circumferential groove l8 and each lower roll is provided with a circumferential rib l9 complementary to the adjacent groove Hi, the grooves and ribs being in alinement and progressively increasing in depth and height respectively, so that during movement of each section A between the sets of rolls, the

embossment is gradually formed, asshown in Fig. 8. The embossments a, a, a are formed by the sets of rolls 4a, 5a, 6a and la. For

-this purpose, the opposite ends of theupper roll 4a terminate in inclined walls 29 and reduced circular ends- 2| and the adjacent lower roll is complementary shaped at its opposite ends. Each of the remaining upper rolls 5a, 6a, 1a is formed at its opposite ends with circumferential grooves 22 and each adjacent lower roll is provided at its opposite ends with complementary annular ribs 23 the depth of these grooves and height of the ribs progressively increasing. As shown in Fig. 2, the sets of rolls 6a, Ia, at one end are shaped to form the embossment e 24, 25, indicate a pair of co-acting devices disposed upon opposite sides of the path of movement of the sections and movable from the rear side of an imaginary median line to the forward side thereof and provided on their opposed faces with transversely extending complementary embossing elements 26, the elements on the lower member intersecting the'plane in which the sections A move, so that the sections, in passing through the co-acting devices, are embossed upwardly as shown at C and downwardly as shown at C (see Figs, 8, 9 and 10).

In the form of construction shown in Figs. 1 to 7, inclusive, the embossing. devices 24, 25, consist of a pair of members respectively keyed to upper and lower rock shafts 24a, 25a, mounted in the bearing boxes I0, which are supported in the standards 8, the extended endsof the shafts 24a, 2511, being provided with segmental gears 21 in mesh with each other, whereby the shafts rock simultaneously in opposite directions. Each member 24, 25, consists of a sleeve 28 keyed to the adjacent shaft and radially extending arms 29, to the outer ends of which are suitably bolted plates 30 provided on their outer sides with embossing elements 26, the embossing elements 26 on one member being complementary to the embossing elements on the other member. By preference,

, the plates 30 are provided with a plurality of sets of embossing elements 26 to provide two parallel embossments C at either side of the embossment B and a downwardly extending terminating edge or embossment C. By preference, I provide an arm 29 at each end of each member 24, 25, and an arm 29 midway therebetween. As will be understood from Figs. 4, 6 and 7, the arms 29 on the member 24 are formed with recesses 29a and the bers 24, 25.

biasing the members 24, 25, to a predetermined arms 29 on the member 25 are provided with ribs 29a to accommodate the embossments a, a, a and B as the sections A pass between the mem- Means are provided for normally position ready to receive a section A between them, as shown in Figs. 3 and 5. For this purpose one gear segment 21 is provided with an arm 32 to" which one end 'of a spring 33 is connected, the opposite end of the spring being suitably anchored, and normally tends to swing the membets :4, 25, to the -pesmen' referred to against a stop 34. The stop 34 preferably consists of a bolt threaded through a bracket 34a, whereby its free end may be adjusted to limit the movement of the gears 2'! at the desired position. The bracket 34a may be provided with a threaded shank and screwed into the wall of the adjacent standard (see Fig. 4). i I

I The members 24, 25, 'are operated from the position shown in Figs. 1, 3 and 5 to the position shown in Fig. 6, the movement thereof being coordinated with the movement of each section A, so that the embossing elements 3| move therewith. In the arrangement herein shown, I provide one of the members (preferably the upper member 24) with 'a device in the path of movement of each section A, so that the advancing front end of the latter swings the members 24, 25, from their normal position forwardly, the spring. 33 serving to move them back to normal position after the rear end of the section has passed the members. For this purpose, the arms 29 on the member 24 are provided on their front sides with brackets 34 to which are suitably bolted blocks 35, the brackets and blocks being formed with recesses in which are clamped the opposite ends of shafts 36. Each of the shafts 36 rotatably supports a roller 31, normally disposed in the path'of movement of each section A. As shown in Figs. 3 and 6, therollers 31 are so positioned that their peripheries are in contiguous relation to the forward edge of the embossing elements 26; accordingly, theadvancing front end of the section engages with the rollers 31 immediately after it passes the elements 26 and as such end continues to advance, it swings the rollers outwardly and upwardly about the axis of the shaft 24a, the effect of which is to operate the members 24, 25; to the position shown in Fig. 6. As the section A continues to advance the rollers 31 ride thereon and thus maintain the members 24, 25, in oper-.

ated position until the rear end of the section passes the rollers, whereupon the spring 33 will swing the members back to normal position. In the arrangement shown, the embossments are positioned adjacent to the front ends of the sections A, but by positioning the rollers in spaced relation to the forward sides of the members 24, 25, the embossments may be provided ata point remote from the front ends of the sections- 38, 38, indicate a pair of feed rolis'keyedto shafts 38a, the opposite ends of the latter being mounted in bearing boxes which are suitably supported by the standards 9. The shafts 38a are geared together,and the lower shaft 38a is provided with a sprocket 39 which is engaged by a chain 40, driven by a sprocket 4| fixed toand driven by thelower shaft Ia, as shown in Fig. 3.

The sprockets 39 and 4| are of similar. size was to drive the shafts 38a at the same speed as that of the shafts la. v

Referring to Figs. 11 and 12 which show a modified form of construction for providing the embossments C, C, in each section, 8? indicates a pair of standards adapted'to be mounted on the frame I between the standards! and 9 and suppath of movement of the sections A. The links are pivoted at their inner ends on shafts 44a supportedby lugs formed integrally with the plates the members 42. The opposed faces of the plates 43, 43a and pivoted at their outer ends on shafts 44a supported by integral lugs 44 provided on 43, 43a, are formed with recesses 45 in which are mounted dies 45' having on their opposed walls complementary embossing elements. The rear ends of the plates 43, 43a, are connected to springs 46, which are suitably anchored to brackets 46::

and normally tend to swing the plates 43, 43a,

rearwardly, as shown in dotted lines, whereby they are separated and positioned to receive a' section A between them, the rearward movement of the plates being limited by the engagement of the rear links 44 ,with stops 41. The upper plate 43 is provided at its front end with rollers 48, mounted similarly to the rollers 31, so as to be engaged by the advancing end of each section A. The plates 43, 430, are providedat their opposite ends with pairs of laterally extending pins 49 which slide in vertically extending, parallel slots 49a formed in plates 50, the plates 50 serving to connect the plates 43, 43a, together whereby theyswing in unison from one position to the other and back again. Accordingly, when each sectionengages with and moves the rollers 48 to the dottedline position X shown in Fig. 11, both plates 43, 43a, will be operated and effect embossing of the section and through the engagement of the rollers 48 with the advancing section, they will remain in operated position until the rear end of the section passes the rollers, whereupon the plates will swing rearwardunder the influence of the springs 46.

The machine herein disclosed is shown em bossing a section of sheet material approximately ten feet long, but it will be understood that the sections may be of any desired length. The embossingrolls 2a, 30., etc., are preferably driven at a rate of speed to feed the sections at approximately 180 feet per minute and they aredelivered successively to the shaping rolls 2a, each spaced from or timed with respect to the preceding section in relation to the'time required for the return movement of the members 24, 25, after the rear end of each section has passed the actuating rollers 31 (Figs. 1,to '7) orrolls 46(Figs. 11 and 12) for operative relation to the front advancing end of the succeeding sectionl The sleeves 28 are positioned on the shafts'24a, 2511 between a collar 5| and ring nuts 62 engage ing threaded portions on the shafts, spacing 53 collars being provided to properly positionthe sleeves.

54 indicates supports for the sections extending between each set of rolls, between the rolls 1a and the embossing members 24, 25, and also from apoint which clears the rollers 31 to the rolls 38. The supports 54 are mounted on-cross members rigidly carried by the standards. The

. between washers, which are held in position by nuts 36' threaded on the shafts.
